ROME (AP) — Pope Leo XIV on Sunday told more than a million Catholic youths at a closing Mass for a weeklong encounter with the next generation of faithful that they are “the sign that a different world is possible” where conflicts can be resolved with dialogue, not weapons.

In a message of solidarity and peace, Pope Leo XIV said the Catholic Church stands with young people suffering in war-torn areas, including Gaza and Ukraine.

Pope Leo XIV urged hundreds of thousands of young people on Saturday to have the courage to make radical choices to do good, as he presided over his first big encounter with the next generation of Catholics during the highlight of the Vatican’s 2025 Holy Year.
